2 Speed Fan Poser will my woes end!

Have just arrived in Portugal having towed my 1420kg caravan with my Cdti Auto remapped 160.
Ran superbly until I came to a very long steep climb in Spain 1400 mtrs over 3/4kms (Hgv's crawling with hazards on) when temp gauge started to rise and engine went into limp mode, tried to keep revs as low as possible and made it with engine fading and picking up several times. Same thing happened after a further 200 kms, and on another nearly as steep climb temp went up but engine didn't fade. Completed rest of journey with no problems including many long steady climbs, gauge not moving from half way car pulling like a train.
Has anyone else experienced anything similar, is it the exceptional climbs with the load or could 2nd fan speed not be kicking in (it runs when a/c is switched on), is it possible to check it? I am sure when I had the remap not long back the fan was checked out ok albeit still with the original silver resistor.
I have a bit of time before the journey home and wonder whether I should be doing anything to give me 'peace of mind'. This is the first time I have towed such a long distance, up until this issue I have never had a temperature problem. Any thoughts would be most welcome.
